How this service works
Mint a bearer session token bound to your wallet. Prepay credits via /credits/buy, open a session here (once), then call /m/<route> with the token to spend credits per call OFF-CHAIN at high frequency — no per-call settlement. The rail for looping agents. Token expires; treat it as a password. Returns {session_token, ns, balance, expires_at}.
Output
Returns a JSON object containing: session_token (bearer token to pass as auth on /m/<route> calls), ns (namespace identifier), balance (remaining credit balance), and expires_at (ISO timestamp when the session expires). The token must be treated as a password and is single-use for opening but multi-use for spending credits.
Example use cases
High-frequency agent loop initialization
“I need to kick off a long-running agent loop that will call the LLM completion endpoint hundreds of times — open a session on x402.shizu.me so the agent can spend credits off-chain without settling each call on-chain.”
Looping web digest pipeline
“My agent needs to scrape and summarize dozens of web pages in rapid succession — open a session token on x402.shizu.me using my prepaid credits so it can call the digest route repeatedly without per-call payment overhead.”
Bounty board polling agent
“Set up a session so my agent can continuously poll the x402.shizu.me bounty board and respond to tasks at high frequency — I've already topped up my credits, just need the bearer token to start.”
Technical details
Endpoint
POSThttps://x402.shizu.me/session/open?utm_source=zero.xyzWhen to prefer
Choose this endpoint when your agent needs to make many calls to x402.shizu.me /m/ routes at high frequency without incurring per-call blockchain settlement costs. It is the necessary first step after buying credits via /credits/buy — you must open a session here before any toll-gated route calls. Prefer this over per-call payment when your workflow involves loops, polling, or burst usage where latency and gas costs of individual settlements would be prohibitive.
Side effects
- Insufficient prepaid credits — session open rejected if wallet has no credit balance
- Wallet not recognized — token minting fails if no prior credit purchase recorded
- Session token expiry — token becomes invalid after expires_at, requiring a new session open
- Duplicate session conflict — opening multiple sessions may invalidate earlier ones
- Network error or service unavailability returns 5xx with no token issued
